Low-risk checklist
- Keep a manual record of every Shell, weapon, and Tarstone found.
- Back up saves before irreversible quest decisions.
- Read boss-specific trophy conditions before entering late fights.
- Do not spend rare materials only to unlock a trophy until the build is stable.

Steam achievements and PlayStation trophies
Steam lists 53 achievements for Mortal Shell II. Source 1Steam Global Achievements for Mortal Shell IIOpen source The specialist PlayStation roadmap also tracks 53 trophies, so both platforms currently point to the same total even though names, descriptions, and hidden-objective presentation can differ.
This guide covers both "Mortal Shell 2 achievements" and "Mortal Shell 2 trophy guide" searches. Use the live list on your platform for exact wording, then follow the route below to plan missables, collectibles, and later playthroughs in one checklist.
Roadmap at a glance
The current roadmap rates the Platinum at 5/10, estimates 20–30 hours, lists 53 offline trophies and no online trophies, and says one playthrough is sufficient after post-launch updates. Those are specialist estimates, not official guarantees. Source 2PowerPyx Mortal Shell II Trophy GuideOpen source
| Stage | Main job | Risk control |
|---|---|---|
| First run | Story, bosses, Shells, weapons, sidearms, Tarstones | Track all four missables before their relevant encounters |
| Post-story | Free-roam cleanup and Shell Memories | Finish the remaining list before choosing New Game+ |
| Optional NG+ | Recovery from a missed repeatable condition or personal replay | Do not enter until first-save cleanup is complete |
The four missables identified by the current roadmap are Mid Summer, Peter's Perfect Parry, No, You Still Can't Win, and Bag Holder. Read their exact conditions on your platform before the relevant quest or fight. The current roadmap lists zero glitched trophies. Source 2PowerPyx Mortal Shell II Trophy GuideOpen source
Collectible discipline
Keep separate counts for all eight Shells, all primary weapons and sidearms, and all Tarstones. Record the region and nearest Beacon immediately after collecting something. A screenshot of the inventory page is safer than memory.
Do not start New Game+ until story cleanup is finished. The roadmap states that free roam remains available after the final boss before entering New Game+, which makes that point the safest general cleanup window.
Save protection
There are three playthrough slots but no ordinary manual save slots, according to the roadmap. On PC, close the game before copying files and follow the save-file backup guide. Cloud synchronization can overwrite the wrong version if files are restored while the client or game is running.
This roadmap was reviewed on August 28, 2026. Trophy bugs and requirements can change, so the live platform list and current patch notes take priority.
Current roadmap facts
PowerPyx currently lists 5/10 difficulty, 20–30 hours, 53 offline trophies, zero online trophies, four missables, zero glitched trophies, one minimum playthrough, free roam after the story, and New Game+. Source 2PowerPyx Mortal Shell II Trophy GuideOpen source This replaces the older multi-playthrough estimate that existed before post-launch resource changes.
Steam independently lists 53 achievements. Source 1Steam Global Achievements for Mortal Shell IIOpen source The matching total does not guarantee identical wording or hidden-objective presentation across platforms, so use the list visible on the system being played.
Protect the two tutorial missables
Mid Summer and No, You Still Can't Win occur in the opening section, and the current roadmap warns that New Game+ starts later and skips that tutorial. Source 2PowerPyx Mortal Shell II Trophy GuideOpen source Read their exact conditions before advancing.
If one is missed, a separate playthrough slot can be safer than overwriting the main save. Make a supported backup before the relevant sequence, but verify cloud behavior first. Do not close or restore during a save write.
Peter's Perfect Parry
This missable is tied to a specific Nameless Captive attack and the Untarnished Seal. The specialist roadmap requires Perfect Guarding the complete qualifying headspin sequence rather than merely surviving or parrying a different variation. Source 2PowerPyx Mortal Shell II Trophy GuideOpen source
Read the current condition before the boss, preserve a backup, and stop attacking when waiting for the required move. If boss health becomes too low, quit through a supported menu path before the fight is irreversibly completed. Patch-sensitive timing should be checked against the current build.
Bag Holder
Bag Holder depends on a particular Baghead interaction path. The roadmap warns that giving the wrong item can miss the trophy for the current playthrough. Source 2PowerPyx Mortal Shell II Trophy GuideOpen source Record the dialogue state before choosing and do not improvise from a vague “complete the NPC quest” summary.
The joke ending can return the player to the nearby Beacon according to the specialist route, but the exact choice sequence should be verified on the live page before use.
First-run collectible plan
Track these groups separately:
- all eight Shells and their bonding state;
- all primary weapons;
- all sidearms;
- all Tarstones required by the live list;
- all Beacons and Ova;
- all map fragments;
- named boss and NPC conditions;
- all Shell Memories.
Use a region and nearest- Beacon field for every pickup. A screenshot of an icon without a location is poor cleanup evidence.
Shell Memories and Seeking the Past
The roadmap documents 40 Shell Memories: five for each of eight Shells. It states that maximum bonding uses 27 Glimpses per Shell and that post-launch changes allow the task in one playthrough through respec and renewable Glimpse sources. Source 2PowerPyx Mortal Shell II Trophy GuideOpen source
View each memory through the Shellkeeper and mark it before resetting a Shell. The specialist warning says resetting can remove the viewed memories from that Shell's menu, so a manual ledger is essential even when the platform trophy counter is hidden.
Weapons, sidearms, and Tarstones
Record the pickup, inventory registration, and nearest Beacon for each item. Do not spend upgrade materials merely to prove ownership unless a separate trophy requires the upgrade. The weapon roster, sidearm guide, and Tarstone guide keep their counts and patch warnings separate.
The Week 1 economy makes Tarcores and Glimpses renewable, reducing the need for old multi-run farming routes. Check current patch notes before following a launch checklist.
Boss and story cleanup
The roadmap allows free roam after the final boss and before choosing New Game+. Source 2PowerPyx Mortal Shell II Trophy GuideOpen source Use that state to finish regions, collectibles, and ordinary upgrade objectives. Do not select the transition into New Game+ until the first-save checklist is complete.
For each boss, read any specific trophy condition before victory, preserve the nearest safe backup, and verify the platform notification before continuing. General boss trophies and missable challenge conditions are different tasks.
No online requirement
All 53 trophies are listed as offline, with zero online trophies. Source 2PowerPyx Mortal Shell II Trophy GuideOpen source Network access may still be used for platform synchronization, patches, or cloud saves. Offline trophy design does not make a cloud backup automatic or guarantee immediate server synchronization.
Save backup discipline
The roadmap reports three playthrough slots and no ordinary manual save slots, although exiting to the main menu can trigger a save. Source 2PowerPyx Mortal Shell II Trophy GuideOpen source On PC, use the save-file guide only while the game and client are closed. On console, use supported platform workflows.
Keep generations before each of the four missables and before entering New Game+. A single cloud copy is not version history.
Confirm an unlock is recorded
After completing a condition, check the platform trophy or achievement list rather than relying only on the pop-up, then mark the item in the same ledger used for collectibles and missables. Preserve the prior save generation until the platform list shows the unlock and the next objective has been recorded.
If a trophy does not unlock
Stop before overwriting the prior state. Confirm the exact live wording, platform account, patch, prerequisite, and whether the interaction completed. Check the platform list rather than relying only on the pop-up. Disable PC mods and reproduce on a clean save copy when possible.
The current roadmap says zero trophies are glitched, but that is not proof that an individual account or new patch cannot have a registration problem. Report the exact objective and evidence without claiming every save is affected.
This guide was fully rechecked on September 3, 2026. It now reflects the current one-playthrough, 20–30 hour, four-missable roadmap rather than the obsolete launch-era multi-run plan.
